Dexamethasone Impurity 61 CAS CATO-C4X-116561 chemical structure

Description

CATO manufactures Dexamethasone Impurity 61 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Dexamethasone Impurity 61 (CAS CATO-C4X-116561) is a certified pharmaceutical impurity reference standard with the molecular formula C22H27FO6 and a molecular weight of 406.44 g/mol.

The molecular framework of Dexamethasone Impurity 61 (C22H27FO6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
